Fig. 281. 335] ELIHU THOMSONS EXPERIMENTS 399 In Figs. 282 and 283, two sine curves, a and a, have beentraced with the same period, but with amplitudes which areas 4:1. The ordinates of the curve b are taken equal to theproducts of the corresponding ordinates of A and a, and aredrawn above the line… … Fig. 282.if it is negative. When the difference of phase is equal to - A (Fig. 282), the attraction and repulsion are equal both in intensityand in duiation, and the resulting effect is therefore nothing. But if the difference of phase exceeds -, and it always does exceed this value, repulsion…
